Subject: [PATCH] platform/x86: thinkpad_acpi: Fix compiler warning about uninitialized err variable
Git-commit: 6229ce9c36384c7adce09f06a3a1897faa5f2c1a
Patch-mainline: v5.18-rc1
References: bsc#1210050
err is always set because if we get here then dytc_profile_available
is always one of DYTC_FUNCMODE_MMC or DYTC_FUNCMODE_PSC, but the
compiler cannot now that, so initialize err to 0 to avoid a
compiler warning about err being uninitialized.
